Fish vaccine injection injuries of the hand.

High pressure injection of oil-based substances can cause devastating injuries of the hand and the necessity for urgent surgical debridement has been well established. We present three cases of injection injury caused by vaccines used in the fish farming industry. Patients presented with pain, swelling and lymphangitis. The marked vascular changes often associated with such injuries were absent. All patients were treated with intravenous antibiotics combined with early surgical debridement and irrigation. We report full recovery in all three patients.

Persistent vertical binocular diplopia after cataract surgery.

PURPOSE: To report the incidence of, and factors associated with, persistent vertical diplopia after cataract surgery. DESIGN: Consecutive interventional case series. METHODS: Retrospectively, all adult patients examined during a five year, five month period because of new onset persistent (>3 months) vertical binocular diplopia after cataract surgery were analyzed. All patients had their cataract surgery at the same outpatient ophthalmic surgery center, and were referred to the author, enabling calculation of incidence. Trends in anesthesia type and strabismus complications therefrom were also assessed. Comparison was made between ophthalmologist-administered retrobulbar anesthesia versus anesthesia staff-administered retrobulbar anesthesia. Incidence during a period in which hyaluronidase was not incorporated in the retrobulbar anesthetic was calculated. RESULTS: Persistent vertical diplopia occurred after cataract surgery in 32 (0.18%) of 17,531 eyes that had cataract surgery. No patient whose cataract surgery was conducted with topical anesthesia (3817 eyes) had persistent vertical diplopia, whereas 32 (0.23%) of the 13714 eyes whose cataract surgery was done after retrobulbar anesthesia were affected. No cases of persistent postoperative diplopia were found among 7410 cataract surgery eyes after retrobulbar injection given by one cataract surgeon. There was a threefold greater number of left eyes involved than right eyes (P <.005). No significant (P >.20) increase in cases of persistent vertical diplopia was noted during a period of hyaluronidase shortage. CONCLUSIONS: In this study, persistent binocular vertical diplopia after cataract surgery occurred in 0.23% of cases in which retrobulbar anesthesia was performed. No cases were found after topical anesthesia. Occurrence may be technique-related.

[Perforation of surgical gloves in gynecologic operations and abdominal Cesarean section].

The aim of the study was to determine the incidence of glove perforation during gynaecological operations and Caesarean section, and to assess the value of double gloving. For this purpose the surgical gloves used in 415 procedures were tested for perforations by the water leak test. For laparotomy and breast surgery, two pairs of gloves (brand A) were worn; for vaginal and other surgery, only a single pair of thicker gloves (brand B) was used. As controls, 75 pairs of unused gloves of each brand were tested. This revealed 6 (4%) perforations in brand A gloves and 2 (1.3%) perforations in brand B gloves. Most perforations (20-40%) occurred during hysterectomy, Caesarean section, and other types of laparotomy. The gloves worn by the scrub nurse or technician were most often perforated (43.5% after vaginal hysterectomy), followed by the surgeon's gloves (29% after laparotomy). Perforations were most often located at the tip of the index finger (16.8%) and thumb (16.2%) of the nondominant hand. If two pairs of gloves were worn, and perforation occurred, only 26.7% had perforations at identical sites on the outer and inner gloves. Consequently, since three quarters of the perforations were limited to the outer glove, double gloving reduced the risk of exposure to blood by a factor of 4. The results of this study support the recommendation that two pairs of gloves be worn, at least during major surgical procedures and Caesarean section. Furthermore, the alternative operative techniques and methods of handling surgical instruments proposed for reducing the incidence of glove perforation should be tested.

Analysis of workplace injuries in a dental school environment.

Workplace injuries at the University of Queensland Dental School during the period 1992-1994 were assessed to determine their incidence, and the associated indirect costs, causal factors, and appropriate preventive strategies. Overall, dental chairside assistants experienced a higher incidence of injuries than students both on a per worker and per time basis. Of the injuries with a low risk of cross-infection, burns and scalds from sterilizing equipment, and eye injuries in laboratories were the most common. This emphasizes the importance of wearing appropriate protective equipment in areas outside the treatment zone, and the need for signage and education. Common causes of sharps injuries were burs left in handpieces, two-handed needle recapping, and cleaning of probes in the sterilizing room. Changes to techniques and equipment would prevent such incidents. A range of factors which contribute to the calculation of indirect costs following injuries in the dental workplace are identified.

Percutaneous injuries in dentistry: an observational study.

The authors conducted an observational study of the frequency and circumstances of percutaneous injuries among dental residents. Their findings suggest that most percutaneous injuries sustained by these dental residents occurred extraorally and were associated with denture impression procedures. Some injuries may be preventable with changes in techniques or instrument design.

Hypodermic needles: a new source of penetrating ocular trauma in Indian children.

PURPOSE: To study the clinico-microbiologic profile and visual prognosis of ocular injuries caused by disposable hypodermic needles used by children to squirt water. METHODS: We analyzed 19 consecutive cases of hypodermic needle injury seen at our institute. RESULTS: The average age of the patients was 10.3 years (range, 4-20 years). A small self-sealed corneal or scleral laceration was seen in 11 eyes; in 8 eyes, the site of injury was occult. Initial visual acuity was no light perception (3 eyes) or hand motion or light perception (16 eyes). Surgery in 18/19 eyes included vitrectomy with intraocular antibiotic injections for endophthalmitis (14 eyes), evisceration for panophthalmitis (2 eyes), and cataract extraction for traumatic cataract (2 eyes). Final visual acuity was no light perception or light perception only in 10 eyes, 20/400-20/60 in three eyes, and 20/40 or better in six eyes. CONCLUSIONS: Severe ocular morbidity may result from improper disposal of hypodermic needles.

Injury reports in a dental school: a two-year overview.

As teaching institutions, it is vital for dental schools to collect data on accidental injuries to identify potential problems, improve the quality of care of patients, and educate future practitioners about risk management. Our data reveal important trends concerning such injuries. These data were compiled over a two-year period (2001-03) from accident reports at one dental school. We categorized the accidents as follows: source (instrument causing the injury), recipient of injury, time of day, location within the dental school where the injury occurred, and body part injured. The population examined in this study consisted of predoctoral and postdoctoral dental students, staff, faculty, and patients of the dental school. The majority of injuries occurred in the predoctoral clinic toward the middle to the end of the scheduled clinic periods. The instrument most likely involved was a needle, and the body part most commonly injured was a finger. The collection and analysis of injury data may be used to identify trends that will aid in the prediction and prevention of these injuries and, at a national level, serve as a benchmark that other dental schools can employ to assess their relative frequency of injury.

Needle prick injury to the surgeon--do we need sharp needles?

Needle prick injury is a well known hazard for surgeons and their assistants. This carries a risk of transmitting HIV and hepatitis infection. In this study the high incidence of sharp needle injury was confirmed (18.9%), with more than one third (8.7%) resulting in skin puncture. The highest incidence of injury occurred during hernia repair (27%) and abdominal wound closure (52%), where injury was sustained to the left index and middle finger as would be expected in right-handed surgeons. Blunt-tipped needles were used in 78 different procedures with technically satisfactory outcome particularly in abdominal wall wound closure and hernia repair, and even in colonic anastomosis, only two glove injuries were reported, with no skin injury. We concluded that the used of blunt-tipped needles is a practical option in eliminating needle prick injury to surgeon's hands.

Retinal detachment secondary to ocular perforation during retrobulbar anaesthesia.

The clinical characteristics and the retinal breaks associated with rhegmatogenous retinal detachments secondary to accidental globe perforation during local infiltration anaesthesia in five highly myopic eyes are presented. Retinal detachment was total with variable proliferative vitreoretinopathy. The pattern of retinal breaks was rather typical and predictable. Management involved vitreous surgery with internal tamponade by silicone oil in four eyes and perfluoropropane gas in one eye. At the last follow-up, all eyes had attached retina. One eye did not recover useful vision due to possible concurrent optic nerve damage.
